An atomizing spray nozzle device 100 includes plural inlets that receive different phases of materials of a coating. The device 100 also includes an atomizing zone housing 522 portion fluidly coupled with the inlets 518, 520 and shaped to mix the different phases of the materials into a mixed phase slurry. The device 100 also includes a plenum housing portion 524 fluidly coupled with the atomizing housing portion 522 along the center axis of the device 100. The plenum housing portion 524 includes an interior plenum 546 that is elongated along the center axis 106 of the device 100. The plenum 546 is configured to receive the mixed phase slurry from the atomizing zone. The device 100 also includes one or more delivery nozzles 526, 528, 530 fluidly coupled with the plenum 546. The one or more delivery nozzles 526, 528, 530 provide one or more outlets from which the mixed phase slurry is delivered onto one or more surfaces of a target object as a coating on the target object.
